[Tarantool-patches] [PATCH luajit] test: fix libfficcall compilation for old GCC

[Sergey Kaplun via Tarantool-patches]

On CentOS 7 GCC has no std=c99 by default. This leads to compilation
warnings and errors for ‘for’ loop initial declarations. This patch
fixes that by declaring the variable out of the loop body.

isn't better declaring outside the loop and define in a loop?

int i;
for (i = 0; i < lengthof(s1.v); i++) {

It looks more familiar this way. Feel free to ignore.
